Message:

Static hash tables no longer need to be coupled with a VM.
<​https://webkit.org/b/135421>

Source/JavaScriptCore:
Now that the static hash tables are using char instead of StringImpl,
it's no longer necessary to make them per-VM.

This patch removes the hook in ClassInfo for providing your own static
hash table getter. Everyone now uses ClassInfo::staticPropHashTable.
Most of this patch is tweaking ClassInfo construction sites to pass one
less null pointer.

Also simplified Lookup.h to stop requiring ExecState/VM to access the
static hash tables.

Source/WebCore:
Update for JSC::ClassInfo changes.

Remove the JSNoStaticTables mode for IDL code generation, which was used to
ensure that each VM had its own unique copy of certain static tables.
This was used for interfaces that could be used in workers, and now there's
no need to manually annotate these things anymore.

Also remove the DOMObjectHashTableMap class that was only used for this.
